Someone Built the PS4 Portable Sony Never Made with a 7-Inch OLED - Yanko Design

"This is not a Raspberry Pi or a cloud device but a heavily modified PS4 Slim motherboard, cut and re-laid to be as compact as possible while keeping full functionality. The builder redesigned the layout for better power efficiency and thermals, then wrapped it in a custom ABS enclosure with full controls and a 7-inch 1080p OLED screen, turning a console into something that looks and plays like a handheld from an alternate timeline."

"The cooling story is where most of the work lives. A new airflow path, custom heatsinks, and a large rear fan are managed by an onboard ESP32 microcontroller. The ESP32 runs custom firmware to watch temperatures in real time, enforce thermal thresholds, trigger emergency shutdowns, and supervise power draw and battery charging. It is the safety brain that makes running a console-class APU in your hands viable instead of a thermal disaster."

"The power system uses six 21700 cells at 6,000 mAh each in a 3S2P configuration, roughly 130 Wh of energy. Under lighter loads, the system pulls around 44W for about three hours of play. In demanding games, it can draw close to 88W and land closer to an hour and a half before shutdown, at around 10V, which protects the pack. There is also a dedicated port for playing on AC."

The power pack uses six 21700 cells in a 3S2P (~130 Wh), yielding about three hours at 44W and roughly 1.5 hours under 88W. The unit includes HDMI out, multiple USB-C ports, a USB 3.0 port, and AC play support.
